Integrated photonic platform with high-speed entanglement generation and witnessing
Gong Zhang, Chao Wang, Koon Tong Goh +10
High-speed generation and efficient entanglement detection on a photonic chip are essential for quantum information applications but hard to achieve due to common photonic chips' m…
Self-testing quantum randomness expansion on an integrated photonic chip
Gong Zhang, Ignatius William Primaatmaja, Yue Chen +7
The power of quantum random number generation is more than just the ability to create truly random numbers$\unicode{x2013}$it can also enable self-testing, which allows the user to…
Security of device-independent quantum key distribution protocols: a review
Ignatius W. Primaatmaja, Koon Tong Goh, Ernest Y. -Z. Tan +3
Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key exchange protocol in terms of security, as it can be performed securely with uncharacterised…
Device-Independent Quantum Key Distribution with Random Key Basis
Rene Schwonnek, Koon Tong Goh, Ignatius W. Primaatmaja +4
Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices to distribute secret keys in an insecure network. It thus represents the ultimate form of…
Computing secure key rates for quantum key distribution with untrusted devices
Ernest Y. -Z. Tan, René Schwonnek, Koon Tong Goh +2
Device-independent quantum key distribution (DIQKD) provides the strongest form of secure key exchange, using only the input-output statistics of the devices to achieve information…
Experimental comparison of tomography and self-testing in certifying entanglement
Koon Tong Goh, Chithrabhanu Perumangatt, Zhi Xian Lee +2
We assess the quality of a source of allegedly pure two-qubit states using both standard tomography and methods inspired by device-independent self-testing. Even when the detection…
Versatile security analysis of measurement-device-independent quantum key distribution
Ignatius William Primaatmaja, Emilien Lavie, Koon Tong Goh +2
Measurement-device-independent quantum key distribution (MDI-QKD) is the only known QKD scheme that can completely overcome the problem of detection side-channel attacks. Yet, desp…
Geometry of the set of quantum correlations
Koon Tong Goh, Jędrzej Kaniewski, Elie Wolfe +5
It is well known that correlations predicted by quantum mechanics cannot be explained by any classical (local-realistic) theory. The relative strength of quantum and classical corr…
All Pure Bipartite Entangled States can be Self-Tested
Andrea Coladangelo, Koon Tong Goh, Valerio Scarani
Device-independent self-testing allows to uniquely characterize the quantum state shared by untrusted parties (up to local isometries) by simply inspecting their correlations, and…
Non-local games and optimal steering at the boundary of the quantum set
Yi-Zheng Zhen, Koon Tong Goh, Yu-Lin Zheng +4
The boundary between classical and quantum correlations is well characterised by linear constraints called Bell inequalities. It is much harder to characterise the boundary of the…
Measurement-device-independent quantification of entanglement for given Hilbert space dimension
Koon Tong Goh, Jean-Daniel Bancal, Valerio Scarani
We address the question of how much entanglement can be certified from the observed correlations and the knowledge of the Hilbert space dimension of the measured systems. We focus…
